Pre-treatment for painting aluminum (aluminum die casting) and zinc die casting, which are difficult for paint to adhere to.
When high quality and adhesion are required for the painting of aluminum (die-cast) and zinc die-cast products, we adopt "chromate treatment," which is a pre-treatment for painting aluminum (zinc). By applying "chromate treatment" to aluminum materials and zinc die-cast products, which are considered difficult for paint to adhere to, we can impart "high adhesion" and "high corrosion resistance." These non-ferrous metal materials often encounter adhesion issues during painting. It is necessary to align the required quality and painting specifications during the design phase of the painting process.

basic information
Hexavalent chromium treatment... Among chromium treatments, it has the best adhesion and corrosion resistance. Due to its high toxicity, it cannot be used for export purposes currently. However, it is still used in domestic construction products. Trivalent chromium treatment... It is adopted as an alternative to hexavalent chromium treatment. Although its performance is inferior to hexavalent chromium, it has become the mainstream for aluminum pretreatment due to the balance of environmental performance and the performance of the treatment film. Non-chromium treatment... It is increasingly being adopted as an alternative to chromium. In the case of hexavalent chromium, it is commonly referred to by product names such as Alodine treatment, and in the case of trivalent chromium, it is referred to as Parkoat treatment. We also accommodate requests for chromium acid treatment alone.

Company information
We are not just a "subcontracted painting factory." Established in 1958, our company has a foundation of painting technology and also specializes in chemical treatment, stripping, and cleaning, functioning as the "external surface treatment department" in your organizational chart. Based on our philosophy of "preparation is eight-tenths of the work," we emphasize participation from the "upstream process" before the drawings are finalized. We conduct test painting on a wide range of metals and difficult materials, and we produce the entire process from assembly, packaging, to delivery, thereby reducing your management workload. Additionally, by being able to perform zinc phosphate treatment in-house, we achieve stable painting quality. Furthermore, our micro-heating stripping technology, which does not use chemicals, maintains the electrical state of the "jigs (hangers)" that influence painting quality. Our approach of "pre-treatment determines painting quality" ensures the stability of the paint film during mass production. Rather than simply "applying specified standards," we work backwards to achieve optimal painting specifications and prevent scratches during transportation, sparing no effort in thorough discussions from the outset. This diligent preparation is the shortest path to preventing rework and minimizing total costs. From the development stage, please utilize the expertise of our specialists as part of your production line.
